Title: Suspension controller
Inventor: ICHIMARU OSAYUKI
IPC: B60G17/015
Filed: 1997-12-26
Abstract: PROBLEM TO BE SOLVED: To ensure improved riding comfort or improved control stability according to the degree of importance properly even when road surface discrimination including a plurality of road surface condition details is conducted. SOLUTION: When it is discriminated that the road surface includes a wavy road condition and a rough road condition (steps S15 and S17), prior to a parameter for wavy road (damping force is kept in a hard condition), a parameter for the rough road (damping force is kept in a soft condition) is set (steps S18, S19). It is thus possible to improve riding comfort with the damping force kept in the soft condition. In conventional techniques, when it is discriminated that the road surface includes a wavy condition and a rough road condition, it is difficult to specify which it is based on for controlling, and it is likely not to conduct control with higher importance. In comparison with this, the control with higher importance can be conducted, thus it is possible to prevent unnecessary anxiety from being given to a driver and an occupant.

Title: Exhaust emission control device for internal combustion engine
Inventor: OKADA KOJIRO
IPC: F02D41/02
Filed: 1998-12-25
Abstract: PROBLEM TO BE SOLVED: To suppress deterioration of fuel consumption by stopping motion of regenerating means since an internal combustion engine is in an operating condition in which a temperature of a storage type NOx catalyst is suppressed to rise, when it is judged that a catalyst regenerating efficiency is less than a predetermined reference value, when purifying function of the storage type NOx catalyst is regenerated. SOLUTION: A storage type NOx catalyst 25 of an exhaust emission catalyst control device 23 storages NOx since nitrate is generated from NOx in exhaust at the time of combustion operation in a lean mode, and exhaust emission control is carried out. In the case where poisoning S rate attains a start reference value, a control mode is switched into a S-purge mode by the NOx catalyst 25, and elimination of SOx stored in the NOx catalyst 25 is started. After completion of S-purge, in the case where it is judged that the poisoning S rate of the NOx catalyst 25 is larger than a final reference value and the S-purge is not completed, judgment of the S- regenerating efficiency is controlled. In the case where the S-regenerating efficiency is higher than a reference value, S-purge control is stopped, unnecessary fuel injection is suppressed so as to prevent deterioration of fuel consumption.
